A question about Streetpass

I'm not too sure how Streetpass works, but from what I understand it benefits certain games. Tomorrow I'm going somewhere that may have a *few* people with 3DSs. Is there any reason for me to bring my 3DS and collect the Streetpasses if I don't have any games that work with it? Can I collect the Streetpasses and use them in the future?---Xbox Live GamerTag: ChozoGhost

Xatu235 posted...I don't have either of those fighting games. Can I still earn the Streetpasses? If so, can I save them and use them in the future if I were to buy one of those games?

Streetpass Mii Plaza saves them as the other person's Mii and notifies you.But no, you can't use them in games you get afterward.---My 3DS FC is 4854-6508-4956.Let me know if you want to add me so I can add you. :)
